title: N,N'-Bis(3-bromo-2-hy-droxy-benzyl-idene)propane-1,3-di-amine.
abstract: In the title compound, C17H16Br2N2O2, the dihedral angle between the benzene rings is 57.7 (3)°. The conformation of the central N-C-C-C-N chain is gauche-anti [torsion angles = -64.2 (4) and -167.8 (4)°]. Two intra-molecular O-H⋯N hydrogen bonds occur. In the crystal, molecules are linked by pairs of C-H⋯O hydrogen bonds, forming inversion dimers.
